New theropod remains and implications for megaraptorid diversity in the Winton Formation (lower Upper Cretaceous), Queensland, Australia
Here we report on a new fragmentary megaraptorid specimen from the Winton Formation, found near the type locality of Australovenator wintonensis. Some of the key recognisable characteristics of megaraptorid theropods are robust forearms and elongated three-digit hands with two enlarged recurved claws on digits I and II (for catching and dispatching prey) and a much smaller digit III claw presumably used for manipulating prey and possibly grooming; small blade like teeth; and relatively gracile hindlimbs built for running. The new specimen is represented by two partial vertebrae, two metatarsals, a pedal phalanx and multiple unidentifiable bone fragments.
